[sane-devel] Canon Lide 220 not working over 1200dpi

[mfoolb bloofm]

That is actually a bit frustrating considering I chose this model based on
the 'fully supported from 75 to 4800 dpi' info found on the sane supported
devices page (consider updating that).
I don't know how to help for the GL chip datasheet info.

Thanks.
